1. Haetaan lähdekoodi.
asmok@ubuntu:~/Bin$ svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
[--]
Checked out revision 11230.
2. Siirrytään hakeisitoon.
asmok@ubuntu:~/Bin$ cd ffmpeg
3. Annetaan sopivia optioita.
asmok@ubuntu:~/Bin/ffmpeg$ ./configure --enable-gpl --enable-pp --enable-swscaler --enable-x11grab --enable-libfaac --enable-libfaad --enable-libmp3lame --enable-libvorbis --enable-libtheora --enable-libx264 --enable-libxvid --enable-libdc1394
4. Kun kaikki tarvittavat dev-paketit on asennettu, niin optiot menevät läpi.
